As usual, ComplexExpand is your friend in such circumstances. In Mathematica 7: ComplexExpand[Conjugate[a b], b, TargetFunctions -> Conjugate] a Conjugate[b] Without the TargetFunctions option: ComplexExpand[Conjugate[a b], b] -I a Im[b] + a Re[b] On 4/21/2010 4:30 AM, slawek wrote: > In[1] := Im[a] ^= 0; Conjugate[a b] > > Out[1] := Conjugate[a b] > > It is not funny, Mathematica 6 properly evaluates the result > > a Conjugate[b] > > What happens? > > slawek > > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
